believe libata uses devm_* and the fsl SATA driver (non-PCI) will
need to work in cases similar to the 44x.
Well, as for sata_fsl, it calls of_iomap() which does The Right Thing.
Fair, but I don't see w

Yeah, right please go ahead. But I wonder whether any BIOS was
actually crazy enough to map mmio region above 4G on 32bit machine.
This is a *hardware* mapping on some non-x86 platforms (like PPC 44x
